You need 4 things for an engine to start. Air, fuel, ignition, and timing (both ignition timing and cam timing)

You need to figure out what is missing for it to start.

The only code it's throwing is PO123 throttle body position sensor, voltage too high...and to add icing to the cake I don't have a vacuum tester or anything at hand to test any part now, wat I had available was on borrowed time. Thanks for ur time/reply.

Well the code may have went away if you disconnected the battery. TPS sensor being out of range could possibly cause starting issues because the ECU doesn't see the right voltage. Usually testing the TPS is fairly easy and can be checked with a simple multimeter. You just need to know how to perform the test.

That will tell you if the part is faulty, and should tell you how to properly adjust the TPS into spec if it needs adjusted or replacement

EDIT: http://troubleshootmyvehicle.com/chr...he-tp-sensor-1

That link should provide the information you need to perform said tests.

I had a similar problem a few years back with my '02 Grand Caravan. It turned out (after about 6 hours of diagnostic time) to be a short in the wiring harness. Let's hope that's not the case with yours!
